(4) Unusual volume of flow or concentration of wastes constituting "slugs" as defined herein.

j. Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed or are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.

k. Any water or wastes which, by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solid which interfere with the collection system, or create a condition deleterious to structures and treatment processes.

Sec. 5 If any waters or wastes are discharged, or are proposed to be discharged to the community or multi-use sewerage system, which waters contain the substances or possess the characteristics enumerated in Section 4 of this article, and which, in the judgment of the Town of Ocean City, may have a deleterious effect upon the wastewater facilities processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Town of Ocean City:

Sec. 10 All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this ordinance shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater", published by the American Public Health Association, and shall be determined at the control manhole provided, or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the community or multi-use sewerage system at the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of hazards to life, limb or property. The particular analyses involved will determine whether a twenty-four (24) hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and Suspended Solids analyses are obtained from 24 hour composites of all outfalls where as pH's are determined from periodic grab samples.

Sec. 11 No statement contained in this article shall be construed as preventing any special agreement or arrangement between the Town of Ocean City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Town of Ocean City for treatment, subject to payment therefore, by the industrial concern.
